Question

Equal masses of $S_2,S_4$ and $S_8$ are taken. Highest number of free species are present in:

• A. $S_2$
• B. $S_4$
• C. $S_8$
• D. all have same number of molecule

Answer 1

The correct option is A $S_2$

The order of molecular weights will be

$S_2<S_4<S_8$.

So, if the the equal masses are taken, then highest number of molecules will be in $S_2$.

So, correct answer is option A.
